We analyse the near-infrared interline sky background, OH and O2 emission in 19 hours of H band observations with the GNOSIS OH suppression unit and the IRIS2 spectrograph at the 3.9-metre Anglo-Australian Telescope. The observations cover a range of sky positions with varying lunar conditions throughout the night. We find that the temporal behaviour of OH emission is best described by a gradual decrease during the first half of the night followed by a gradual increase during the second half of… 

Spatial and Temporal Stability of Airglow Measured in the Meinel Band Window at 1191.3 nm

We report on the temporal and spatial fluctuations in the atmospheric brightness in the narrow band between Meinel emission lines at 1191.3 nm using a λ/Δλ = 320 near-infrared instrument. We present

An advanced scattered moonlight model for Cerro Paranal

The largest natural source of light at night is the Moon, and it is the major contributor to the astronomical sky background. Being able to accurately predict the sky background, including scattered

PRAXIS: an OH suppression optimised near infrared spectrograph

The problem of atmospheric emission from OH molecules is a long standing problem for near-infrared astronomy. PRAXIS is a unique spectrograph which is fed by fibres that remove the OH background and

Sky background subtraction with fiber-fed spectrographs

Fiber-fed spectrographs can now have throughputs equivalent to slit spectrographs. However, the sky subtraction accuracy that can be reached on such instruments has often been pinpointed as one of


This paper presents the conceptual design for a new method for the suppression of OH emission lines at near-infrared (NIR) wavelengths by actively adjusting the aperiodic fiber optic Bragg gratings

On the origin of core-to-core variations in multi-core fibre Bragg gratings

Fibre Bragg gratings have been demonstrated to be a powerful tool with which to filter atmospheric emission lines from astronomical spectra. Multicore fibre technology has the potential to simplify

Photonic ring resonator filters for astronomical OH suppression.

This paper derives the design requirements for ring resonators for OH suppression from theory and finite difference time domain simulations, and finds that rings with small radii are required to provide an adequate free spectral range, leading to high index contrast materials such as Si and Si3N4.

MARCOT Pathfinder at Calar Alto progress report

MARCOT Pathfinder is a precursor for MARCOT (Multi Array of Combined Telescopes) at Calar Alto Observatory (CAHA) in Spain. MARCOT is intended to provide CARMENES, currently fiber-fed from the CAHA

Photonic lantern behaviour and implications for instrument design

The empirical photonic lantern model was incorporated into an end-to-end PRAXIS performance model which was used to optimise the design parameters of the instrument and proved particularly important in selecting the optimum on sky field of view per fibre and in modelling the instrument thermal background.

Arbitrary on-chip optical filter using complex waveguide Bragg gratings

We demonstrate a Complex Waveguide Bragg Grating (CWBG) which can be designed to generate an arbitrary transmission spectrum. A comprehensive design method, based on the Layer Peeling/Adding



The case for OH suppression at near-infrared wavelengths

We calculate the advances in near-infrared (NIR) astronomy made possible through the use of fibre Bragg gratings to selectively remove hydroxyl emission lines from the night sky spectrum. Fibre Bragg

New approach to atmospheric OH suppression using an aperiodic fibre Bragg grating.

An aperiodic fibre Bragg grating is demonstrated which performs 94% suppression of OH emission in the 1.50-1.57microm window at a resolving power of R=10,000, a working prototype for a device which will allow comparable levels of OH suppression at R=50,000 across the entire near infrared (1.0-2.0microm) spectrum.

A Calibrated Measurement of the Near-IR Continuum Sky Brightness Using Magellan/FIRE

We characterize the near-IR sky background from 308 observations with the Folded-port InfraRed Echellette (FIRE) spectrograph at Magellan. A subset of 105 observations selected to minimize lunar and

Suppression of the near-infrared OH night sky lines with fibre Bragg gratings - first results

The background noise between 1 and 1.8 ?mu m in ground-based instruments is dominated by atmospheric emission from hydroxyl molecules. We have built and commissioned a new instrument, the Gemini


The near-infrared is an important part of the spectrum in astronomy, especially in cosmology because the light from objects in the early universe is redshifted to these wavelengths. However, deep

The COBE Diffuse Infrared Background Experiment Search for the Cosmic Infrared Background. II. Model of the Interplanetary Dust Cloud

The COBE Diffuse Infrared Background Experiment (DIRBE) was designed to search for the cosmic infrared background (CIB) radiation. For an observer confined to the inner solar system, scattered light

I present a technique to remove the residual OH airglow emission from near-infrared spectra. Historically, the need to subtract out the strong and variable OH airglow emission lines from 1 to 2.5-μm
